AC ISSUE

Hi all,

i am having an issue with my g20,where when i set the temperature manually to 22c ,hot air come from the footwell and cold air from the top vents. how ever if i set it to 20c or below then cold air comes from the footwell. also. i noticed that when the car engine auto stops in traffic it works well even at 22C. I took the car to the dealer and they mentioned that it a software issue my out side air (hot air) flab opens 45% .

still they cant figure it out why the hot air flap opens when footwell setting is set to 22c and airl flow to footwell only .

anyone else experiencing this issue, can you guys check and let me know please.

The temperature out of the face-level vents is independent from the a/c set temperature and is configurable from the a/c menu.

I'd hope the dealer is taking that into consideration and understands the way ambient and target temperatures also influence and change the face level temperatures.

Also, at least one test is conducted with the face level set at mid position, to have similar temperatures at all outlets. Then change cabin temperatures to see how it functions.

BTW, the OP can test that out. Try with menu face values at mid range.
